Companion Push Notification Certificate Update


Usually, Apple related certificates and tokens are valid for one year, like the Apple Push Notification Service Certificate or tokens for the Device Enrollment and Volume Purchase Program and you are already familiar with the process of renewing these certificates and tokes by yourself. When you are deploying the Companion application to managed devices, you know that e.g., Push Notifications are informing your users. To ensure this direct communication between Silverback and the Companion application, an additional certificate is required. This certificate is the Companion Push Notification Service for iOS & iPadOS and is located in the Admin and Certificate section in your Silverback Management Console. As this certificate is also valid for a one year period, this certificate needs also to be replaced every year. Usually the certificate is coming with the last Silverback Release within this period, so if you are keeping Silverback always up-to-date, the certificate will be replaced with the Silverback updates. You will find always the information in the Release Notes, if the certificate has been updated. In case, the new Silverback release won't match the expiration date of the certificate or you won't be able to update Silverback, you can use this guide to replace the Companion Push Notification certificate within just a few clicks. After completing this guide, you will have renewed your push certificate for Companion, allowing users to get notifications within the app for policy settings and file sync notifications.

For cloud customers, the certificate will be automatically updated with a hotfix or new release prior to expiration. There is no need to contact our support in this event.
